  "abstract": "Introduction\n\nTobacco quitlines deliver no-cost evidence-based tobacco use treatment, but many quitline callers continue smoking after a single round of treatment. The aim of this study was to evaluate the representativeness of follow-up quitline treatment reach and effectiveness to inform efforts to enhance quitline re-treatment among adults experiencing socioeconomic disadvantage.Methods\n\nSecondary analyses used recruitment, self-report, and salivary cotinine data collected from participants in a randomized controlled trial evaluating smoking cessation interventions among previously treated quitline participants with socioeconomic disadvantages recruited in Wisconsin from 7 June 2018 to 25 January 2023. Logistic regression analyses examined differential population representation occurring in re-treatment outreach, screening, enrollment, and biochemically confirmed abstinence.Results\n\nProactive outreach was more likely to reach previously treated quitline callers who were aged >45 years (adjusted odds ratio, AOR=1.69-2.33; 95% CI: 1.55-2.63), male (AOR=1.16; 95% CI: 1.08-1.25), Black (AOR=1.18; 95% CI: 1.08-1.30), health-insured (AOR=1.26; 95% CI: 1.11-1.67), less nicotine-dependent (AOR=1.11; 95% CI: 1.02-1.20), co-using alternative tobacco products (AOR=1.46; 95% CI: 1.25-1.70), or living with chronic disease (AOR=1.12; 95% CI: 1.05-1.21). Interest in trial screening was higher among quitline participants who were aged <65 years (AOR=1.45; 95% CI: 1.25-1.89), Black (AOR=2.32; 95% CI: 1.95-2.76), living with chronic disease (AOR=1.34; 95% CI: 1.18-1.53), and had more than a high school education (AOR=1.59; 95% CI: 1.36-1.85). Exclusion criteria differentially excluded Black participants (AOR=1.59; 95% CI: 1.27-2.00) and those with lower nicotine dependence (AOR=1.88; 95% CI: 1.49-2.36). Among trial enrollees, abstinence rates were higher among women (AOR=2.04; 95% CI: 1.37-3.03) and Hispanic (AOR=5.73; 95% CI: 2.68-12.21) participants. Individual differences did not significantly predict treatment engagement or interaction with treatment interventions in predicting abstinence.Conclusions\n\nQuitline re-treatment outreach to previous users of the quitline may help to close gaps in tobacco treatment among socioeconomically disadvantaged older adults and Black people. Relaxing smoking heaviness and frequency criteria may improve representation of Black people in quitline re-treatment trials. Additional research is needed to guide efforts to improve the representation of groups experiencing disadvantage in quitline trials.",
